Fountain of uncreated light

1 Fountain of uncreated light!
Thou give of the mental sight!
Thy beams on all are shed;
Thy grace, on all mankind bestow'd,
Still points each seeking soul the road
To happiness and God.

2 Lighten'd by thine interior ray,
Thee ev'ry child of Adam may
His unknown God explore,
And, following close thy secret grace,
Immerge into the glorious place
Where darkness is no more.

3 That universal light thou art,
And turn'd to thee the darkest heart
A glimmering spark may find;
Let man reject it or embrace,
Thou offerest thy saving grace
To us and all mankind.

4 Light of our soul, we follow tee
In humble faith on earth to see
Thy perfect day of love,
And then with all thy saints in light
To gain the beatifick sight
Which makes their heaven above.
